Bypassing the iCloud Activation Lock on an iPhone 4S running iOS 9.3.6 is possible, but truly "free" and functional methods are rare
and often come with major trade-offs. The most reliable ways involve using an Arduino Uno USB Host Shield to run a hardware-level exploit. Reliable Hardware-Based Methods (Recommended)
Because the iPhone 4S uses an A5 chip, modern software-only bypasses often fail on this model. Community experts generally recommend hardware exploits for a permanent (untethered) fix. Arduino + USB Host Shield : This is the "gold standard" for A5 devices. You use an Arduino Uno USB Host Shield
to put the device into "pwned DFU" mode, allowing you to delete the Sliver Mac
is a popular tool used in conjunction with this hardware to remove the setup screen. Raspberry Pi Pico
: A newer, more stable, and often cheaper alternative to the Arduino method for "hacktivation". Legacy iOS Kit
: Some users recommend downgrading the device to iOS 6.1.3 using the Legacy iOS Kit (works on Linux/macOS) and then hacktivating it there. Software-Only & "Tethered" Bypasses
These methods are often free but may be "tethered," meaning you must re-run the tool every time the phone restarts. iRemove Tools
: Offers a free "tethered" bypass for iPhone 4S on Windows, but the device will not have cellular signal (calls/SMS) after the process. DNS Bypass
: A temporary "trick" where you change your WiFi DNS settings to a specific server (e.g., 104.154.51.7
). This allows you to use a custom interface to browse the web or watch videos, but it unlock the phone for normal use. Critical Limitations to Consider No Cellular Service
: Almost all free bypass methods result in a device that functions as a "WiFi-only" iPod. Calls, SMS, and cellular data will typically not work. iCloud Services
: You will likely be unable to sign into iCloud, use iMessage, or sync with the App Store normally without advanced tweaks. Scam Warning
: Avoid websites that ask for payments via social media or "donations" for a download; many are fronts for malware or scams. Legitimate Official Solution
For an iPhone 4s running iOS 9.3.6, a "full" iCloud bypass is typically achieved using a combination of specialized hardware and software. Because this device uses the A5 chip, it requires a hardware-level exploit to enter a specific state (pwned DFU mode) that software alone cannot trigger on this firmware. Core Feature: Arduino-Based Hardware Bypass
The most reliable free method for this specific device and version involves using an Arduino Uno and a USB Host Shield. This hardware setup executes the checkm8-a5 exploit to bypass the activation check.
Pwned DFU Mode: Uses the Arduino to send a specific exploit payload that puts the iPhone 4s into a "pwned" state, allowing the system to accept unauthorized commands.
Setup.app Removal: Once in this state, software like Sliver (Mac) is used to delete or rename the Setup.app file, which is the application responsible for the "Hello" and iCloud activation screens. iphone 4s ios 936 icloud bypass free
Filesystem Access: Allows the user to mount the device's filesystem via a Ramdisk to modify system files. Common Tool Features
If you use third-party bypass tools (like those from iRemove or Sliver), they often include these specific features: Bypass iCloud Activation Lock in 5 MINUTES (2026)
Bypassing the iCloud activation lock on an iPhone 4s running iOS 9.3.6 typically requires specialized hardware or official Apple procedures, as standard software-only "free" bypasses are often unreliable. Official Recovery Methods
The only permanent and fully functional way to remove an activation lock is through official channels:
Apple ID Credentials: Sign in with the original Apple ID and password on the device. Alternatively, use iCloud Find My to remove the device from the account remotely.
Apple Support Request: If you have legitimate proof of purchase, you can submit an Activation Lock support request to Apple. Technical Bypass Methods (Unofficial)
Community-developed methods exist for older devices like the iPhone 4s (which uses the A5 chip), but they are complex and often require additional hardware:
Arduino + USB Host Shield: This is the most widely recognized technical method for bypassing the iPhone 4s. It involves using an Arduino Uno and a USB Host Shield to put the device into "pwned DFU mode" to delete the Setup.app file.
Sliver Tool: Once the device is in pwned DFU mode via Arduino, a Mac-based tool like Sliver can be used to complete the bypass.
Limitations: These methods are typically "tethered," meaning you may need to repeat steps if the device restarts. They also often disable cellular signals and other iCloud services. Important Considerations
Checkra1n Compatibility: Note that the checkra1n jailbreak does not officially support the iPhone 4s or iOS 9.3.6; it is designed for newer A7-A11 devices on iOS 12 and above.
Security Risks: Be cautious of "free" third-party software downloads that claim to bypass iCloud without hardware; these are frequently scams or contain malware.

iPhone 4s iOS 9.3.6 iCloud Bypass: Free Methods & Important Warnings (2026)
Finding a free iCloud bypass for an iPhone 4s running iOS 9.3.6 is a common challenge for those who have inherited or purchased older Apple hardware without the original credentials. While the iPhone 4s is a legacy device, the Activation Lock remains a server-side security measure that is difficult to circumvent.
Below is a comprehensive guide on the available free methods, their limitations, and the risks involved. 1. Official & Legitimate Free Methods (Recommended)
Before attempting third-party tools, always try the official channels provided by Apple. These are the only permanent and secure ways to unlock a device. Bypassing the iCloud Activation Lock on an iPhone
Original Owner Removal: If you can contact the previous owner, they can remotely remove the lock. They simply need to log in to iCloud.com/find, select the iPhone 4s, click Erase iPhone, and then click Remove from Account.
Apple Support Request: If you have proof of purchase (the original receipt), you can submit an Activation Lock Support Request. This service is free and will permanently unlock the device through Apple's official database. 2. Community & Third-Party Bypass Methods
For users without proof of purchase, several community-driven methods exist for legacy A5-chip devices like the iPhone 4s. The DNS Bypass Method
This is a "partial" bypass that changes the DNS server in your Wi-Fi settings to redirect the device to a custom portal.
How it works: In the Wi-Fi settings, tap the "i" icon, select Configure DNS, and enter a server address based on your region (e.g., USA: 104.154.51.7). Pros: Free and requires no computer.
Cons: It does not actually unlock the phone; it only allows you to browse the web or use specific apps within a simulated interface. Hardware-Based Exploits (Checkm8 & Arduino)
Because the iPhone 4s uses the A5 chip, it is vulnerable to hardware-level exploits.
Arduino + USB Host Shield: Many legacy enthusiasts on communities like r/setupapp recommend using an Arduino board and a USB Host Shield to put the device into a "pwned DFU" mode. This allows you to delete the activation files manually.
Legacy iOS Kit: This is a popular open-source tool used on macOS and Linux that can help "hacktivate" or downgrade the device to iOS 6.1.3, which often avoids the Activation Lock screen entirely. 3. Comparison of "Free" Tools
Several software packages claim to offer one-click bypasses for the iPhone 4s.
I can’t help with bypassing iCloud activation locks or any instructions to remove device security—those steps are illegal and unsafe. If you own the device, here are lawful options:
If you want, tell me which lawful option you prefer and I’ll give concrete next steps.
Bypassing the iCloud Activation Lock on an iPhone 4s running iOS 9.3.6 is difficult because the "Checkm8" exploit, which is popular for newer legacy devices, has limited effectiveness for this specific hardware and firmware combination Legitimate Removal Methods
The most reliable and free way to remove the lock is through official channels: Original Credentials : Sign in to iCloud.com/find
with the original Apple ID, select the device, and click "Remove from Account". Apple Support : If you have original proof of purchase, you can submit an Activation Lock support request Free Alternative Methods
If you cannot use the official methods, these community-driven workarounds are often used for older devices:
Bypassing the iCloud Activation Lock on an iPhone 4S running iOS 9.3.6 is a common request for those trying to revive older hardware. While Apple's official stance is that Activation Lock is a permanent security feature, several community-driven methods exist for this legacy device. 1. The Reality of Free Tools Contact the original owner and ask them to
Many tools marketed as "free bypasses" for iOS 9.3.6 are often unreliable or limited in functionality. Most community members recommend using legacy-specific toolkits rather than modern commercial software.
Legacy-iOS-Kit: A popular community tool used to manage older devices, including downgrading and potentially removing setup.app (the activation screen).
Sliver: Often cited in legacy jailbreak communities as a way to "hactions" (hack-activate) devices like the iPhone 4S and iPad 2. 2. Hardware Requirements
Bypassing the iPhone 4S (which uses the A5 chip) is significantly more difficult than the iPhone 4 because it is not vulnerable to the same easy bootrom exploits.
Arduino + USB Host Shield: To use most effective bypass methods on an A5 device like the iPhone 4S, you typically need an Arduino Uno and a USB Host Shield. This hardware allows you to send the necessary "pwned DFU" commands that software alone cannot achieve on this specific model. 3. Functional Limitations
Even if a bypass is successful, it is rarely a "full" unlock.
No SIM Services: Bypassed devices usually cannot make calls or use cellular data because the activation records are not officially signed by Apple.
Tethered vs. Untethered: Some free methods are "tethered," meaning the device will lock again if it is restarted.
App Compatibility: iOS 9.3.6 is very old; many modern apps will not download from the App Store even after a bypass without a jailbreak and specific tweaks. 4. Official & Safer Alternatives
If you are the rightful owner, these are the only guaranteed and safe ways to regain access:
Apple Support: You can request an Activation Lock removal if you can provide original proof of purchase.
iCloud.com: If you have access to the Apple Account, you can sign in to iCloud Find My and select Remove from Account to unlock the device instantly.
DNS Bypass: A "soft" bypass where you change your Wi-Fi DNS settings to a specific server. This doesn't unlock the phone but lets you use a web-based interface to watch videos or browse the web on the device.
This paper explores the challenges and opportunities of using legacy Apple devices (specifically the iPhone 4s running iOS 9.3.6) for entertainment and lifestyle purposes in the 2020s. It addresses the issue of iCloud activation lock not as a bypass guide but as a legal and ethical barrier, reviewing Apple’s official解锁 (unlocking) procedures, the device’s limited app ecosystem, and its viability for music playback, podcast streaming, basic photography, and retro gaming. The paper concludes that while security restrictions are necessary, they also accelerate planned obsolescence, raising questions about digital preservation and consumer rights.
| Error | Solution | |-------|----------| | "Exploit failed" | Re-enter DFU mode. Try a different USB port (use USB 2.0, not USB 3.0). | | Stuck at "Sending iBSS" | Replace your Lightning cable. Try a shorter cable. | | Phone reboots to lock screen | The bypass did not persist. Run the tool again immediately after reboot. | | No Wi-Fi after bypass | Go to Settings > Wi-Fi > Forget the network and re-add it manually. |
Let's be clear: A free bypass is not the same as an official unlock.
